Steam-carbon dioxide electrochemical conversion in solid oxide electrolysis cells (SOECs) is one of the efficient ways to reduce CO2 emission and to simultaneously store the renewable power. In this study, H2O-CO2 coelectrolysis performance and syngas synthesis in solid oxide electrolysis tubular cells at different operating temperature (700-850 oC) is tested. The results indicated that the coelectrolysis performance for Ni-YSZ/YSZ/LSM-YSZ electrolysis cell increases significantly with operating temperature. In addition, syngas yield was analyzed with various operating conditions such as the reaction composition, total flow rate, current density, and so on. Also, the pressurized coelectrolysis module system which is configured on the tubular SOEC cells is being developed. |
